Entry: shiva (n.)
In context: "His own late obstetrician father had rended his own clothing in symbolic shiva in the Year of the Whopper..."
Updated (thanks Daedalus):
Shiva (Hebrew: שבעה) (literally "seven") is the week-long mourning period in Judaism for first-degree relatives: father, mother, son, daughter, brother, sister, and spouse. The ritual is referred to as "sitting shiva." Immediately after burial, first-degree relatives assume the halakhic status of "avel" (Hebrew: אבל ; "mourner"). This state lasts for seven days, during which family members traditionally gather in one home (preferably the home of the deceased) and receive visitors. At the funeral, mourners traditionally rend an outer garment, a ritual known as keriah. This garment is worn throughout shiva.
